摘要
本文研究了一种非最小电压应力无源无损软开关PWM变换器，与具有最小电压应力的PWM变换器相比，它具有电流应力更小，效率更高的优势。作者分析了非最小电压应力无源无损电路网络的无桥Dual—Boost功率因数矫正（Power Factor Correction，PFC）变换器的工作模态，并且给出了相应的参数设计。仿真结果证实了该方案的可行性。
A non-minimum voltage stress lossless passive soft-switching PWM converter is analyzed in this paper. Comparing with the PWM converter of minimum voltage stress, it has the advantages of smaller current stress and higher efficiency. Furthermore, the authors analyze the operating model of the bridgeless dual-boost PFC converter which is of the non-minimum voltage stress lossless passive circuit network and the corresponding parameter design is given. The simulation result verifies the feasibility of the scheme.
